Description

Methods & Sampling

Dataset acquisition description

Adult Acropora palmata colonies were sampled (1 cm2) with hammer and chisel and tissues were preserved in 96% non-denature Ethanol. DNA was extracted using the DNEasy tissue kit (Qiagen) following manufacturer’s instructions. Two multiplex Polymerase Chain Reactions (PCR) were performed per sample using fluorescently labeled primers to assay five loci containing AAT repeats. These five microsatellite loci have previously been demonstrated to be mendelian and coral-specific using controlled crosses (Baums et al., 2005). PCR products were visualized with an automated sequencer (ABI 3730). An internal size standard (Gene Scan 500-Liz, Applied Biosystems CA) ensured accurate sizing. Electropherograms were analyzed with GeneMapper Software 3.0 (Applied Biosystems, CA). Alleles were scored as PCR product size.

Data Processing Description

Dataset Processing Description

Electropherograms of microsatellite alleles were scored for allele sizes (basepairs) in Genemapper vers. (Applied Biosystems) and transferred to spreadsheets.

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- nd (no data) was entered into all blank cells
- replaced spaces and / with underscores
- converted the submitted multilevel table to a flat table

VERSIONS: 2017-21-26: Replaced version 1 (2016-11-30) with version 2 (2017-10-19). There was a shift in 1 basepair at locus 181 for some of the data.

Instruments

Automated DNA Sequencer

Supplied Name: automated sequencer (ABI 3730)

Supplied Description:

Instrument Type

Generic Name: Automated DNA Sequencer

Acronym: Automated Sequencer

Generic Description:

General term for a laboratory instrument used for deciphering the order of bases in a strand of DNA. Sanger sequencers detect fluorescence from different dyes that are used to identify the A, C, G, and T extension reactions. Contemporary or Pyrosequencer methods are based on detecting the activity of DNA polymerase (a DNA synthesizing enzyme) with another chemoluminescent enzyme. Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it, one base pair at a time, and detecting which base was actually added at each step.

Thermal Cycler

Supplied Name: ABI 3730

Supplied Description:

Instrument Type

Generic Name: Thermal Cycler

Generic Description:

A thermal cycler or "thermocycler" is a general term for a type of laboratory apparatus, commonly used for performing polymerase chain reaction (PCR), that is capable of repeatedly altering and maintaining specific temperatures for defined periods of time. The device has a thermal block with holes where tubes with the PCR reaction mixtures can be inserted. The cycler then raises and lowers the temperature of the block in discrete, pre-programmed steps. They can also be used to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid diagnostics.
